Abstract: PROBLEM TO BE SOLVED: To effectively prevent engine stall of an internal combustion engine provided with a supercharger and a motor for raising supercharging pressure of the supercharger and improve overall performance of the internal combustion engine. SOLUTION: ECU 100 performs an engine stall prevention process in parallel with a fuel injection process. In the engine stall prevention process, ECU 100 operates a motor of MAT 206 to assist rise of supercharging pressure when rotation speed Ne of an engine 200 gets less than a threshold rotation speed A. An upper limit value Qf of fuel injection quantity defined as limit to generate material to be removed such as smoke rises with accompanying rise of actual supercharging pressure Pr by assist by the motor, and quantity of fuel which can be injected increases. Consequently, fuel to secure low speed torque can be injected in low rotation speed zone and engine stall can be prevented. Also, ECU 100 operates MAT 206 in a period other than transient period to raise supercharging pressure as high as possible. COPYRIGHT: (C)2007,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To provide an internal combustion engine equipped with a supercharger and a driving means for assisting the supercharger and avoiding deterioration of power performance. SOLUTION: The engine 200 is equipped with a MAT (Motor Assist Turbocharger) 206. In a transitional operation period of the engine 200, when assist capacity of the MAT 206 becomes insufficient due to, for instance, insufficient remaining power of a battery 219 or the like and an actual charging pressure Pr become lower than a target charging pressure Pa, increase correction is made to a reference injection quantity specified according to the actual charging pressure Pr. In this case, a correction amount is calculated based on a differential pressure between the actual charging pressure Pr and an estimate charging pressure Pest estimated on the assumption that the maximum assist capacity is provided by the motor.

Abstract: PROBLEM TO BE SOLVED: To improve fuel economy of a vehicle by accurately controlling a drive amount of a motor.
SOLUTION: As engine rotation speed NE is higher, base assist amount Dn(%) is calculated smaller (step 102). As a gear position is in lower gear position side, namely gear ratio is larger, coefficient k is established smaller (step 104). Final assist amount Df (%) is calculated (step 106) by multiplying base assist amount Dn and the coefficient k. When battery voltage is higher than a predetermined value, the motor is driven by the final assist amount Df(%) (step 110).
